    Re: Scale a small area plotting sheet?
    From: Bill Lionheart
    Date: 2016 Mar 1, 19:35 +0000

    I just tried Ed Popko's postscript files.  Postscript is a good
    language for this sort of work (and I am old enough to remember when
    we had to program in it to draw stuff on laser printers). Ed's code is
    well documented and easy to customize without any knowledge of
    PsotScript. I changed the paper size to A4 for example with these
    lines
    
    /wid {595 pt} bind def            % Paper width A4
    /hgt {842 pt} bind def            % Paper height
    
    replacing
    
    /wid {8 in} bind def                % Paper width
    /hgt {10 in} bind def            % Paper height
    
    for example.
    
    Is the idea to print them out for the Lat and Long that you expect to
    sail before you set off? I have not had much luck with a printer on
    the boat.  Isn't that where the ones with just a compass rose and you
    draw your own scale win?
